From what I understand to get Annex-M ADSL2 support on Cisco routers you need to get a hardware upgrade/replacement and IOS 12.4(11).
New versions of the 877 routers with a "-M" and a "HWIC-1ADSL-M" have been released for various other routers.
What I wish to know is if there is going to be any new WIC-1ADSL part with Annex M support (aka WIC-1ADSL-M).
Hi, I don't think there will be any evolution for the older WIC, because the higher rates require in fact the highest bus speed that only HWIC's have.
Hope this helps, please rate post if it does!
